Application of Corona Wind to Practical Tubular Heat Exchangers

Abstract

A corona wind was used to improve the performance of practical tubular heat exchangers. Rates of heat transfer were measured for each exchanger, which was exposed to a corona wind produced by applying a negative high voltage to several needle electrodes placed above the exchanger.
The usefulness of the corona wind in improving exchanger performance was confirmed through comparison between the rates of heat transfer under corona wind and those under natural convection.
